CY2077FZZ

Product Overview

The CY2077FZZ from Cypress Semiconductor Corp is a single-circuit clock generator intended for surface-mount timing designs. It accepts clock or crystal inputs and provides CMOS and TTL outputs, with a PLL and divider/multiplier functions. The device operates from 3.3 V or 5 V supply rails and is specified for an operating temperature range of 0°C to 70°C. It is supplied in an 8-TSSOP package with 0.173" (4.40mm) body width.

Key Features

• Clock generator with integrated PLL.
• Input options include clock or crystal.
• Output logic families include CMOS and TTL.
• Divider and multiplier functions are available.
• One circuit is provided, with a 1:1 input-to-output ratio.
• The specified maximum frequencies are 100 MHz and 133 MHz.
• Supply voltage options are 3.3 V and 5 V.
• Operating temperature range is 0°C to 70°C.
• Surface-mount 8-TSSOP package with 0.173" (4.40mm) width.

Applications

• Generating local clock signals for digital logic boards using crystal or external clock inputs.
• Driving CMOS or TTL timing inputs in digital assemblies.
• Providing PLL-based frequency division or multiplication in general-purpose timing subsystems.

Design & Procurement Notes

When selecting the CY2077FZZ for a design, verify that the required timing architecture is compatible with a single-circuit clock generator using non-differential clock or crystal inputs and CMOS/TTL outputs. The 1:1 input-to-output ratio and available divider/multiplier functions should be checked against the target frequency plan, while the 100 MHz and 133 MHz maximum frequency values should be considered with the supply selection of 3.3 V or 5 V. Because the device is surface-mount in an 8-TSSOP package and specified for 0°C to 70°C, layout, thermal management, and operating environment should be reviewed accordingly.
